Abstract: Cleansing compositions, e.g. a shampoo, comprising coconut oil fatty acids, oleic acid, propylene glycol and triethanolamine and an industrial cleansing composition comprising neutral alkali metal soaps, lanolin and sodium lauryl sulphate contain as a biocidal agent a quaternary ammonium benzosulphimide or a halogen complex thereof. Typical examples of such compounds are dodecyl benzyl trimethyl ammonium benzosulphimide, cetyl trimethyl ammonium benzosulphimide and lauryl isoquinolinium benzosulphimide.  The above biocidally active compounds may also be incorporated into petroleum products, e.g. jet fuels and lubricants, to prevent biological degradation.ALSO:Quaternary ammonium benzosulphimidehalogen complexes are prepared by adding a halogen or a halogen complex, e.g. Kl3, to a 10% aqueous solution of a quaternary ammonium benzosulphimide, e.g. dodecyl trimethyl ammonium chloride or stearyl trimethyl ammonium benzosulphimide.  Alternatively, a solution of a quaternary ammonium-halogen complex, e.g. of an alkyl dimethyl benzyl ammonium chloride and iodine may be added to a solution of sodium benzosulphimide to produce the desired complex.ALSO:Polymers are rendered anti-static by incorporating therein a quaternary ammonium benzosulphimide or a halogen complex thereof. In an example, alkyl dimethyl benzyl ammonium sulphimide, cetyl trimethyl ammonium benzosulphimide, dodecyl benzyl trimethyl ammonium benzosulphimide, alkenyl dimethyl ethyl ammonium benzosulphimide and lauryl isoquinolinium benzosulphimide are incorporated into "Epolene E" (Registered Trade Mark for a polyethylene wax).  Reference is also made to mixing the active compounds with epoxy resins, phenolics, acrylates, cellulose esters, polyolefines, polyurethanes, polyvinyls and nylon.  The active compounds also have biocidal activity which is imparted to the plastics.ALSO:Paper, textiles, skins, leathers, furs and plastics may be rendered anti-static by treatment with a quaternary ammonium benzosulphimide or a halogen complex thereof. Reference is made to coating sheeps of "Epolene E" (Registered Trade Mark for a polyethylene wax) with dodecyl benzyl trimethyl ammonium benzosulphimide, cetyl trimethyl ammonium benzosulphimide, alkyl dimethyl benzyl ammonium benzosulphimide, lauryl isoquinolinium benzosulphimide and alkenyl dimethyl ethyl benzosulphimide. Drinking cups, toothbrush handles and bristles and plastics toys may be coated with the above quaternary ammonium compounds wherein they act as bioxidal and dirt-preventive agents.ALSO:Biocidal compositions comprise a carrier and a quaternary ammonium benzosulphimide or a halogen complex thereof.  They may be in conventional cosmetic and pharmaceutical forms e.g. shaving creams, after-shave lotions, creams, lotions, brilliantines, shampoos, face powders, foot powders, toothpastes and mouthwashes, industrial cleansing compositions, eye lotions and ear drops.  Typical active compounds are dodecyl benzyl trimethyl ammonium benzo-sulphimide; cetyl trimethyl ammonium benzo-sulphimide and lauryl isoquinolinium benzo-sulphimide.
